[GIT PULL] x86/entry for 7.0-rc1

[Dave Hansen <dave.hansen@linux.intel.com>]

Hi Linus,

Please pull some x86/entry changes for 7.0-rc1. This is entirely
composed of a set of long overdue VDSO cleanups. They makes the VDSO
build much more logical and zap quite a bit of old cruft. It also
results in a coveted net-code-removal diffstat.

There have been a few bumps along the way with this series, thus the
bug fixes on top. But nothing too scary.
